The car belonged to a performance tuning company. I dont remember which one it was.... it was on SVTPerformance last year. I was given a website for it and it stated that after that video was shot, the car was totalled in a wreck. I believe it did have an off-road X and a Maggie setup like mine. They gave the specs on the mods and all. It sounds like mine as well.
I just dont remember which company it was. I know they didnt try and rebuild another terminator, they got a new 05 GT and were putting a Pro-Charger on it. Thats all I can remember. There is a site with this car on it though.
Dude post that up on SVTPerformance and I bet that company will sing out with the website for you.
